| Abstract: | The effect of cathode GDL with various carbon loadings on stability of neat methanol feed passive DMFC and passive water management was investigated.Water loss and methanol efficiency were quantitatively calculated.The results show that the increased carbon loadings of cathode GDL is helpful to reduce water loss and enhance methanol efficiency.A neat methanol feed passive DMFC stack with a maximum power of 8.3 W was successfully designed and fabricated to power a digital calendar. |
